Batches Application of High-fluidity 3D Printing Aluminum Alloy Powder

(Batches Application of High-fluidity 3D Printing Aluminum Alloy Powder)

High-quality spherical metal powder is an important guarantee for
high-performance metal additive manufacturing. Its composition, oxygen content
and powder physical properties (morphology, particle size distribution, powder
fluidity, loose density, etc.) have an impact on the stability and manufacturing
process of 3D printing. The physical and chemical performance of the parts is
very important, which affects and determines whether the product can be
installed and applied.

Among the many technical indicators of powder, the sphericity of the powder
and the ratio of satellite spheres directly affect the fluidity and bulk density
of the powder. Low powder sphericity or too high proportion of satellite spheres
will directly affect the powder feeding or spreading quality, which in turn
affects the quality of printed parts, and produces internal and surface defects.
In recent years, with the increasing maturity of additive manufacturing
technology, the demand for efficient forming of complex components and large
parts has become higher and higher. Smart additive manufacturing factories have
also emerged, but they are limited by the bottom-mounted powder supply mode in
equipment operation. In the process, it is impossible to add powder online, and
the opening and adding powder is prone to step connection and metallurgical
defects. Therefore, the international mainstream large-size equipment usually
adopts the continuous powder feeding system of the upper feeding type. The upper
powder feeding method has higher requirements on the fluidity of the powder. 

If
the powder fluidity is not good, the powder will fall unevenly, or there will be
agglomeration or unevenness in the powder spreading process, which will
adversely affect the print quality. In the future, the demand for high fluidity
powders in metal additive manufacturing will become more and more prominent.

Aluminum alloy powder is not easy to obtain high fluidity due to its light
density, and the morphology control of the preparation of aluminum alloy powder
is more difficult than other alloy materials, so that for a long period of time,
the aluminum alloy powder used for 3D printing only has an angle of repose.
Evaluate powder fluidity, but can not be directly measured with a Hall flow
meter. At present, high-fluidity aluminum-based alloy powder materials
(AlSi10Mg, etc.) have been used in batches in aerospace, automotive
transportation and other fields, and the powder product characteristics and
printed parts have good performance. The 3D printed test block was prepared with
high-fluidity AlSi10Mg powder, and small pores were occasionally seen in the
horizontal and vertical surfaces of the metallographic form, and there were no
large pores.
